' Specification of Letters Patent.

Patented Apr. 9, 191s.

Application led June 29, 1917. Serial No. 177,733.

To all whom t may concern: Y

-Be it known that I, SMITH H. ELLIOTT, a and a resident of Walthill, in the county of Thurston and State of Nebraska, have invented certain new and' useful improvements in Tank- Heaters, of which the following is a speciiication. 1

The .presentV invention' relates to tank heaters. v I l Thev'invention aimsv to provide animproved heater for stock-waterers, or other water containers.

A further object of the invention is the production of la simplified and inexpensive oil heater embodying certain novel features adapting it to be readily installed within and removed from a water tank.

With these and other objects in view, the invention, consisting in' the construction, -combination and novel arrangement of parts, will be clearly understood from the following description, reference being had to the accompanying drawings, which form a part of this application, and in which like characters of reference indicate corresponding parts throughout the several view, of

- which,-

Figure 1 1s a vertical section of an advantageous embodiment of the invention installed in a water tank; Fig. 2 is a side elevation of the burner; Fig. 3 is a plan of the same; Fig. 4: is a vertical section of vthe jet; and Fig. 5 is a plan of the circulating coil.

Referring, now, to the illustrations, 6 represents a stock watering tank, on the bottom of which is set the heater comprising a casing, 7, having a bottom, 8, and a draft flue, 9, at its upper end which extends above the water line. The casing communicates at its side with a large `air inlet flue, 10, extending obliquely a distance above the water line. Within the flue 10, and secured to the bottom thereof, is a pipe, 11, extending above the Hue and having its upper end turned downwardly' and introduced into a tank, 12, supported by the pipe, and adapted to contain oil to be forced by pressure into the pipe, 11. The pipe is provided with a controlling valve, 13.

The burner consists of a horizontal pipe coil,'14, preferably spiral-shaped and having its outer end portion turned downwardly, as at 15, to receive from the pipe, 11, and support the coil. The inner end porl tion of the coil is turned downwardly, as.v

at 16, and. provided with acap, 17, threaded thereon and preferably so'V related thereto that there is a space 24 between the end of the cap and the end of the said portion of'r the coil. The end of the cap is provided with a lcentral opening, 18, which freely incloses aplug, 24, having-a conical head, 25, seated on the end of the cap to cover' the opening and support the plug. Theplug Serves asa jet, Vhaving an axial bore, 26, for

l the emission of the gas.

The conical head, 25, prevents accumulation of carbon, and otherV by-products of the fuel, at a point where it could obstruct the jet bore, for obviously refuse material will not remain on the head but drop into the space around the head and between the end of the cap and the end of the coil, which space is readily cleaned by forcing the plug upwardly and inserting a suitable instrument into the hole 18, to remove the contents of the cap.

Below the burner is a saucer, 19, having an ear, 20, slidably supported by and releasably fixed to 'the pipeportion, 15, by means of a set-screw, 21, whereby the saucer may be adjusted toward and from the'jet.

' Above the saucer is a pipe-coil, 22, having superposed helices, the end portions of said coil being extended through and Secured to the wall of the casing as by nuts, 23, on the opposite sides of the wall.

To light the burner, the sauceris filled with oil from the jet and then lighted toy heat the coil, 14., `whereby the oil is converted into a gas which ignites at the jet. Obviously the flame from the jet is forced against the saucer which spreads and refleets the flameto heat both the coils, 14, and 22. y l

It is evident the Water is heated by being siphoned through the heated coil, 22.

Having thus described my invention what I claim as new and desire to secure b v Letters Patent of the United States is,-l

l. A heater including an oil container, a feed pipe to receive therefrom, and a burner including a spiral pipe coil having its outer end extended downwardly and connected with the feed pipe to receive from the feed pipe, the inner end of the coil being extended downwardly and provided with a jet, and a saucer supported by said first portion below the coil, adjustable toward and from the'coil, and adapted to receiveoilV 2. A heater including an oil container, ak

feed pipe to receive therefrom, and a burner including a spiral pipe coil having its outerV end tportion extendeddownwardly and connected with the feed pipev'to receive from thel feed pipe and support the coil, the inner end of the coil being extended downwardly and provided withaj et, and a saucer supported byvesaid first portion below 1the coil, and adapted to receive oil to heat the'l coil and Splcadand reflect the Haine from the jet.

A heater ,including a pipecoil having a downwardly turned en d, a vcap Vthereon having an vopening in its end, and a vjet includingV a plug `freely inclosed by said opening, andhaving a passage therethrough and aheadonthe plugeresting" on the end of the cap to close the opening, and support-the plug. L 4. Aaheaterincludinga pipe coil having a. downwardly directed end, a Cap thereon having an opening in its end and a jet 1nv cluding a'plugl freely .inclosed by Said opening, having a-gas passage therethrough and 'a-`conical head on the plug resting on the end of the cap to close the opening and preventaccumulation of refuse on the plugfafnd around it ,here

5. A heater including a pipe coil having a downwardly directedend, acap `Vthreadedthereon, and f so `related thereto astroA provide a space k between the end of the Ac oil andthe end of 4the cap, the cap having an jopenin in its end, and a jet including aplug freely HQlOSd by the Opening, having- L-,eas pas@ sage `and a' conical headresting on the eind of the cap to close the opening and prevent` ac; cumulaton of refuse 01,1' the plug and around its bore. v y.

In testmpny whereof, I have hereunto Set my hand this 245thlday of June, `19V-17.`
